- What is the first equation of motion?
- v = u + at
- This equation relates final velocity (v), initial velocity (u), acceleration (a), and time (t).
- What is the second equation of motion?
- s = ut + ½ at²
- This equation gives the displacement (s) of an object in time (t) with initial velocity (u) and acceleration (a).
- What is the third equation of motion?
- v² = u² + 2as
- This equation relates the final velocity (v), initial velocity (u), acceleration (a), and displacement (s).
- Which equation of motion is used to find final velocity?
- First equation
- The first equation, v=u+atv = u + atv=u+at, is used to calculate the final velocity of an object in motion.
- Which equation of motion is used to calculate displacement?
- Second equation
- The second equation, s=ut+½at2s = ut + ½ at²s=ut+½at2, helps in finding the displacement of an object.
- Which equation is derived from the combination of the first and second equations?
- Third equation
- The third equation, v2=u2+2asv² = u² + 2asv2=u2+2as, is obtained by eliminating time (t) from the first two equations.
